| (54) | METHOD OF MEASURING A FLUORESCENCE SIGNAL, DETERMINING A PEAK FREQUENCY MAP AND PROVIDING A RISK PREDICTION VALUE, IMAGE CAPTURING AND PROCESSING DEVICE |
| (57) An image capturing and processing device 2 configured to measure a fluorescence signal
in a tissue of a body part 4 and to image a surface of the body part. The device 2
comprising a fluorescence imaging unit 22 configured to capture a fluorescence image
7 and a visible light imaging unit 24 configured to capture a visible light image
5. The fluorescence imaging unit 22 is further configured to capture a time sequence
of fluorescence images 7. A peak frequency map unit 60 is configured to determine
a peak frequency map for an area of interest in the fluorescence images by analyzing
the time sequence of fluorescence images 7. The analysis comprising: determining a
time-dependent intensity curve, identifying peaks in the time-dependent intensity
curve and determining a frequency of the identified peaks and/or a maximum high of
the identified peaks, generating a graphic representation of the determined frequency
and/or maximum high and including the same in the peak frequency map. An output unit
is configured to output the peak frequency map together with the visible light image
5 and/or the fluorescence image 7.
